2012 VOLKSWAGEN BEETLE Visibility Problems

I NOTICED A SET OF CRACKS NEAR THE TOP OF MY WINDSHIELD, APPROXIMATELY AT THE POINT WHERE THE REAR VIEW MIRROR ATTACHES AND EXTENDING UP TO THE ROOF LINE EDGE. THE CRACKS WERE APPROXIMATELY 6" - 8" IN LENGTH. I HAVE NO IDEA WHEN OR HOW IT OCCURRED AS I DO NOT RECALL ANY STONE OR OTHER ROAD DEBRIS HITTING THE WINDSHIELD, THERE WAS NO SOUND OF ANYTHING HITTING THE WINDSHIELD OR SMALL CHIP IN THE GLASS WHERE THE IMPACT WOULD HAVE OCCURRED. I DID NOT PARK IT UNDER A TREE AND NOTHING FELL ON OR HIT THE GLASS TO MY KNOWLEDGE. I HAVE HEARD SIMILAR REPORTS FROM OTHER 2012 VW BEETLE OWNERS, AND IT WAS SUGGESTED THAT SOME WINDSHIELDS WERE INSTALLED IMPROPERLY AND COULD LEAD TO STRESS FRACTURES. THERE ARE A LIST OF SIMILAR COMPLAINTS FOUND AT: HTTP://FORUMS.VWVORTEX.COM/SHOWTHREAD.PHP?5560318-CRACKING-WINDSHIELD-AND-ANNOYING-RATTLE-ON-2012-BEETLE. *TR
